Wingware Python IDE

The Intelligent Development Environment for Python Programmers

The source code editor auto-saves files to disk every few seconds. The
auto-save files are placed in a subdirectory of your User Settings
Directory.

If Wing ever crashes or is killed from the outside, you can use these
files to manually recover any unsaved changes. Copy the auto-save files to
overwrite the older unsaved files, doing a comparison first to verify
that the auto-save file is what you want.
